Anaconda – UnsatisfiableError: The following specifications were found to be in conflict

Create a new conda environment for Python 2.7:

conda create -n my_pymc_env python=2.7

Activate it:

conda activate my_pymc_env

Alternatively, for older conda versions on Windows:

activate my_pymc_env

on Unix (including Mac OS X):

source activate my_pymc_env

Once activated, install your packages:

conda install pymc blaze

If you still get this message, install the Anaconda client:

conda install anaconda-client

and search for your package:

anaconda search mypackage

Look for a channel that has the right version for you and install:

conda install -c channel_with_right_version mypackage
